ROBERT MAINER, OF ORILLA, ONTARIO, CANADA, ASSIGNOR TO HIMSELF ANDCHARLES MOINNES, OF SAME PLACE.

IMPROVEMENT IN STOVE-PIPE JOINTS.

Specification forming part of Letters Patent No. 183,315, dated October17, 1876; application filed March 25,1876.

To all whom it may concern Be it known that I, ROBERT MAINER, of Orilla,Province of Ontario, Canada, have invented a new and Improved Stove-PipeJoint, of which the following is a specification:

The accompanying drawing represents a sectional side elevation of myimproved stovevpipe joint.

My invention relates to an improved stovepipe joint of superiorconstruction, by which the danger of fire is avoided, wire supportsdispensed with, and only a short connection of pipes at the ends,instead of a wide overlapping joint, is required.

The invention consists of rivets at the end of one stove-pipe enteringinto slits of the other stove-pipe end, and being locked by pivotedfastening-hooks of the same.

In the drawing, A represents a stove-pipe, which is provided with two ormore rivets, B, that project at the outside of the pipe, and enter thecorresponding slots C of the connecting stove-pipe D. Hooks E arepivoted to the stove-pipe D near the slots or recesses C, and carriedover the rivets or pins B, where the same are inserted into the slots.

The rivets and slots secure the stove-pipe ends against being turnedaxially, while the hooks lock them rigidly together, so as to form astiff and reliable joint.

There is no danger of fire from the accidental separation of the pipes,while the rigid joint dispenses with wire supports, except at ROBERTMAINER.
